1. A method for controlling wireless transmission of power in accordance with safety restrictions, comprising:

  • receiving, via an application executing on an electronic device that is coupled to a wireless power receiver, user-selected safety restrictions used to determine when wirelessly delivered power may be transmitted to the wireless power receiver;

    determining, using data provided by a sensor of the electronic device, whether any of the safety restrictions are present at the electronic device;

    upon determining that the safety restrictions are not present at the electronic device, receiving radio frequency (RF) power waves that are sent to the electronic device by a wireless power transmitter, wherein the wireless power transmitter only transmits the RF power waves when the safety restrictions are not present at the electronic device; and

    while receiving the RF power waves;

    continuing to determine whether any of the safety restrictions are present at the electronic device; and

    upon determining that at least one of the safety restrictions is present at the electronic device, ceasing to receive the RF power waves from the wireless power transmitter.
